CVE-2026-42233: CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in n8n-io n8n
An SQL injection vulnerability exists in the Oracle Database node's select operation in n8n versions prior to 1. 123. 32, 2. 17. 4, and 2. 18. 1. The flaw allows user-controlled input passed into the Limit field via expressions to be directly interpolated into the SQL query without proper sanitization or parameterization. This can enable an attacker to inject arbitrary SQL commands and potentially exfiltrate data from the connected Oracle database. The issue has been addressed in the specified patched versions.
AI Analysis
Technical Summary
n8n is an open source workflow automation platform. Versions before 1.123.32, 2.17.4, and 2.18.1 contain a vulnerability in the Oracle Database node's select operation where the Limit field accepts user input that is not sanitized or parameterized. This improper neutralization of special elements in SQL commands (CWE-89) allows SQL injection attacks when external input is passed into the Limit field, such as from a webhook. The vulnerability has been fixed in the stated versions.
Potential Impact
Successful exploitation allows an attacker with the ability to influence the Limit field input to inject arbitrary SQL commands into the Oracle database query. This can lead to unauthorized data exfiltration from the connected Oracle database. The CVSS 4.0 score is 5.3 (medium severity), reflecting network attack vector, low attack complexity, and partial privileges required.
Mitigation Recommendations
A fix is available in n8n versions 1.123.32, 2.17.4, and 2.18.1. Users should upgrade to these or later versions to remediate this vulnerability. No additional vendor advisory content is provided, so patch status beyond these versions is not confirmed here.
